ObjectiveAneurysmal subarachnoid hemorrhage (aSAH) is associated with high early mortality rates. Cerebral vasospasm remains the major source of morbidity after aSAH. Angiographic evidence of vasospasm is apparent in 70% of patients, while clinical manifestation of vasospasm is present in one third of patients. Early or existing vasospasm at the time of presentation poses an additional challenge in the management of the patient, and forms the basis for this review.MethodsTreatment modalities for management of ruptured aneurysms in the setting of vasospasm, including timing of aneurysm surgery and peri-operative management, are reviewed. Intraoperative measures aimed at treatment of existing vasospasm and at the prevention of vasopasm are discussed.ResultsOperative/endovascular means to secure the ruptured aneurysm should be performed as soon as possible to facilitate treatment of the vasospasm. Surgery performed in the presence of angiographic/symptomatic vasospasm can be associated with good outcome. Operative measures to decrease the incidence of vasospasm include clot removal, intracisternal injection of thrombolytics, fenestration of the lamina terminalis and local application of vasodilatory agents. Post-operative measures include early intra-arterial injection of vasodilators (verapamil or nicardipine), percutaneous angioplasty, triple-H therapy and CSF drainage.DiscussionThe utilization of a multimodality approach to treat patients with aneurysmal subarachnoid hemorrhage presenting with existing vasospasm can result in good outcome.
